concentration measurement on ballmill silica

  • Understanding Units of Measurement

    Concentration (ug/m3) = 0.0409 x concentration (ppb) x molecular weight Or concentration (ppb) = 24.45 x concentration (ug/m3) ÷ molecular weight Here is an example. The molecular weight of benzene is 78. If the concentration of benzene in air is 10 mg/m3 convert to the units of ppm by multiplying 24.45 x 10 mg/m3 ÷ 78 = 3.13 ppm.
